Abstract: A stop assist device is equipped with an operation switch that is operated to activate and deactivate a hazard lamp of a vehicle. The stop assist device starts stop assist control for stopping the vehicle through automatic deceleration of the vehicle and starts activating the hazard lamp from an abnormality detection timing when it is determined that an abnormality condition that is fulfilled when a driver falls into an abnormal state in which the driver is unable to drive the vehicle is fulfilled. The stop assist device continues to perform stop assist control when the operation switch is operated before the lapse of a predetermined invalid time from the abnormality detection timing during the performance of stop assist control, and ends stop assist control when the operation switch is operated after the lapse of the invalid time from the abnormality detection timing during the performance of stop assist control.

Abstract: A powder magnetic core having excellent specific resistance or strength. The powder magnetic core has soft magnetic particles, first coating layers that coat the surfaces of the soft magnetic particles and include aluminum nitride, and second coating layers that coat at least a part of the surfaces of the first coating layers and include a low-melting-point glass having a softening point lower than an annealing temperature for the soft magnetic particles. The first coating layers including aluminum nitride are excellent in the wettability to the low-melting-point glass which constitutes the second coating layers and suppress diffusion of constitutional elements between the soft magnetic particles and the low-melting-point glass of the second coating layers. The powder magnetic core can stably exhibit a higher specific resistance and higher strength than the prior art owing to such a synergistic action of the first coating layers and second coating layers.

Abstract: A method is provided where an anode of an all-solid-state lithium ion secondary battery is easily doped with lithium and to provide a small resistance at a low battery capacity. The method includes a manufacturing method of a cathode including mixing at least a conductive assistant (C1) and a sulfide solid electrolyte (E1) to obtain a mixture; and mixing at least one cathode active material, a solid electrolyte (E2) and the mixture obtained from the first step to obtain a cathode mixture, wherein an amount of energy added to the sulfide solid electrolyte (E1) is larger than an amount of energy added to the solid electrolyte (E2), and the mixture is a material that releases lithium ions at a potential lower than a potential at which the cathode active material releases and occludes lithium ions. Manufacturing methods for a cathode and an all-solid-state lithium ion secondary battery including the cathode mixture are also disclosed.
